7 Claims.

'I'his invention relates to improvements in window constructions and has for one of its objects to provide an improved window of simple and practical construction wherein a locking mechanism is provided which is operative to lock a window sash in any position of adjustment thereof.

Another object is to provide a novel form of locking mechanism and operating means therefor in which said mechanism includes a plurality of locking elements and a control member having relative movements therebetween for wedging said elements against the frame of the window and in which operating means is operable to release certain of said elements from locking contact with said frame as a sash therein is being raised or lowered.

The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawings which illustrate a preferred embodiment of the inventive idea.

In the drawings:

Figure l is a front elevation of a window constructed in accordance with the present invention and of a type wherein the window space is adapted to be closed by a plurality of upper and lower sashes.

Figure 2 is a fragmentary vertical longitudinal section through the window frame and one set of upper and lower sashes,

Figure 3 is a fragmentary horizontal section through the window construction shown in Figure 1.

Figure 4 is a fragmentary vertical section through the lower sash illustrating the locking mechanism of the present invention in the normal locking position that it assumes after the sash has been adjusted to either closed, fully opened, or partially opened positions.

Figure 4a is a fragmentary vertical section of a portion of the mechanism which forms a continuation o-f the upper end of the vertical side of the sash down in Figure 4.

Figure 5 is a View similar to Figure 4 illustrating the lower locking element in its released position which is assumed as the sash is being lowered.

Figure 6 is an edge elevation of the sash showing the lower locking element in the position of Figure 4.

Figure 7 is a View similar to Figure 6 showing said locking element actuated by the operating member to a released position as in Figure 5J and condition. As shown in Figures 1 to 3, the window is of the type comprising vertical series of upper and lower sashes I0 and II, there being three of such series shown in Figure l with mullions I2 interposed between adjacent vertical edges of the pairs of sashes to provide guides will be understood, of course, that windows may be employed, such lower sash, without materially altering the lockof the present invention or further understood that when series of sashes such as shown in Figures 1 and 3 are employed, a locking mechanism illustrated in detail on the other figures of the drawings is utilized with each one of the sashes, the mechanism for each upper sash being inverted from the position shown in Figure 4 wherein the mechanism is illustrated in connection with a lower sash in which the window opening, including the head I3 sill I4 and the vertical side jambs I5, is lined by the metallic substantially rectangular frame, generally indicated by the numeral I6, having vertically oiset channels therein formed by a series of guide strips I1 which are adapted to receive the upper and lower sashes I0 and I I. Each of the sashes cornin detail in connection with one of the lower sashes II such as illustrated in Figures 4 and 4a and, as previously indicated, this locking mechanism is duplicated in each of the upper sashes I 'J except that it is located in an inverted position from that assumed in the lower sash.

The locking mechanism is preferably contained within the sides i8 and bottom rail 20 of the lower sash and, as shown in Figures 4 and 4a, comprises a lock control element generally indicated by the numeral 22 positioned within each of the sides I8 of the sash and consisting of an elongated strip which is secured to the inner wall of said side by suitable fasteners such as the the scope thereof. It will be a Y recess formed by the Y 32 and 341, respectively,

screws 23. The element 22 further comprises the spacedupper and lower projecting portions 25 and 25, respectively, having the eiective surfaces 25 and 2l thereof inclined in opposite directions. These surfaces combine with the outer wall 28 of the side i3 to form wedge-shape recesses adapted to receive therein the upper and lower locking elements 2S and 39. These elements may take the formof either ball or roller bearings which are yieldably supported in their respective recesses by means of steel or springs 3l carried by the upper and lower ends of therrespective portions 2Q and 25. The upper locking element 2t is adapted to be projected by its associated. spring 3i throughV an elongated opening 32 formed in the outer wall 28 otthe side I8 opposite the inclined surface 26, so that said vlocking element will engagel the stile 33 of 'the frame it and thereby become wedged between said surface 26 and the stile so as to lock the sash Il against upward movement when an attempt is i made to raise the sash by any other means than the operating member to be presently described. Likewise, the lower locking element 3B is projected through an elongated opening 3.1i inthe Wall 2B so that it will be wedged between the surface 2 and the stile`33 to lock the sash against downward movement. us the locking elements 29 and 33 will cooperate to lockfthe sash H in any position of adjustment thereof and will maintain said sash in such position'until one or the other locking the operating member presently to be described, to recede within its recess against the action or" the associated spring 3l. If the adjustment of the sash to be made is in an upward direction the locking element 2s is positively Yforced into its inclined surface 25, whereas if, the adjustment is downward the locking element 3Q is forced downwardly into its recess. During an upward adjustment of the sash, the contact of the element 3e with the stile will produce suicient friction to cause said element to move downwardly into its recess formed by the surface 2i against the tension of the spring 3i, while during a downward adjustment of the sash the element 23 will likewise be caused to moved into its recess so that neither of said elementsl will interfere with the easy sliding movement of the sash if the other element has been positively actuated by the operating member.

The operating means for the locking elements 29 and 3i! of the lowerrsash il preferably comprises a U-shaped operating member generally indicated by the numeral 35 which is located within said sash and which consists of the single horizontal channel bar 33 extending through the bottom rail 2t, and the two vertical channel bars 3l each of which extends longitudinally of one of the sides i3 of the sash yin cooperation with the locking means in said sides. At spaced points along the intermediate wall of each bar 3l, which wall engages the interior surface of the outer wall 28 of the side I8, said intermediate wall is provided with elongated upper and lower slots 33 and 39 which are in registrationwith the openings in the outer wall 28 so that the locking elements through said slots. In the normal position of the operating member 35, shown in Figure 4, the horizontal bar 3i? thereof situated medially of the upper and lower edges of lower'end or. the upper slot 33 is located adjacent the locking element 23, and the upper end of the slot 39 is spaced slightly from the locking elehard bronze coilY elements is positively actuated, by

29 and 33 will project the rail 2Q, theV ment 3D. Intermediate the ends of the bottom rail 2c of the sash the interior side thereof is provided with a vertically disposed slot 4B and in alignment with said slot the bar 35 of the operating member carries a block or enlargement M to which a handle i2 is secured by means or a screw G3, said handle being utilized to manipulate the operating member 35 when raising or lowering the sash. The normal or intermediate position oi the operating member 35 is maintained by the provision of a coil spring lie located within each o the sides i3 and interposed, as shown in Figure 4a, between the upper endY oi the upper portion 2d of the element 22 and an inturned flange i5 at the upper end of the vertical bar'l,

In practice, should it be desired to lower the sash Il from a fully orpartially opened position, the handle 132 is grasped and forced downwardly, the initial movement of this handle being relative to the rail 2! owing to the slot it therein,

latter the upper end of the slot 39 in each bar 31V will contact its associated locking element 3), as illustrated in Figures 5 and '7. Thereafter a con-- tinued downward movement of saidV operating member will cause said locking element to recede within its recess against the action of its associatedV spring 3l so that said locking element will no longer cause a between the inclined surface 21 and the stile33.

At the same time, the downward movement of the Y sash relative to the stile 33 permits the latter, by reason of its contact with the locking elementi@ to force said element inwardly intoits recess so that nov binding action will occur at this point. When the locking elements 29 and 3@ have thus been released, the latter by the positive action ci upon said handle will now move the sash in the desired direction. During this movement the spring has been compressed by reason offthe downward pressure of Vthe flange @5' thereagainst and as a consequence, when the desiredV position r of the sash hasrbeen attained and the handle i2 released, the spring Se will expandY and thereby cause a lifting action upon the operating member 35 until it has per end of the slot 3S has been moved away from wedging action to be produced Vthe bar 31, and the handle Q2 has reached the bottom of the slot el), further downward pressure s been restored to its normal intermediate position. When this occurs the upthe locking element 3e, whereupon the associated spring 3! will Vagain force said element upwardly and outwardly into ment with the stile 33. In a like manner when it is desired to raise the sash il, a lifting action upon the handle e2 will cause the lower endoi the slot 38 in each of the bars 3l' to raise the locking or wedging engageassociated locking element 29 against the action l of its spring so that said element will recede into its recess and at the same time the locking element 3!! will move slightly into its recess b-y reason of the rictional contact thereof with the stile 33.

ments has been so effected, the portion of the handle extended through the slot 40 will engage the upper end of the latter and continued upward pressure will then raise the sash to the operating member 35 will drop of its own weight After therelease of said Vlocking ele- Y Y desired position. Upon release of the handle, the

until the flanges 45 again contact the upper ends of the springs 44 which thereupon act to center bar 36 of the operating member within the rail 20.

As previously explained the locking mechanism just described is duplicated in each of the upper sashes I but in an inverted position and is operated, in a manner which will be clear from the foregoing description, by means of handles 46 carried by the upper rails 2| of the upper sashes.

A weather-proofing strip 41 (Figure 2) may be secured to the meeting rail I9 of the lower sash and overlap the space between said meeting rails and a similar weather strip 48 may depend from the exterior surface of the bottom rail 2U so as to overlap a part of the sill portion of the frame I6.
